Application filed August 25, 1917.

To all whom it may concern:

Be it known that I, OSCAR KATZENBERGER, a citizen of the United. States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented a new and Improved Spring-Hinge, of which the following isa full, clear, and exact description.

This invention relates to spring hinges, and has for an object theprovision of an improved construction for protecting the spring, whileat the same time producing a nice appearance.

Another object in view is to provide a spring hinge having a. barrelformed with notches and caps on the ends of said barrel covering thenotches for giving a better appearance to the entire structure and atthe same time protecting the spring against the elements.

In the accompanying drawing:

Figure 1 is a perspective view of a spring hinge embodying theinvention.

Fig. 2 is a detail perspective view of one of the caps disclosingcertain features of the invention.

Fig. 3is a longitudinal vertical section through the barrel part of thehinge shown in Fig. 1.

Fig. 4 is a sectional view through Fig. 3 on line 4.-t.

Referring to the accompanying drawing by numerals, 1 and 2 indicate theleaves of a spring hinge, which leaves are provided with ears 3 and A ateach end through which the pintle 5 extends. A spring 6 is coiled aroundthe pintle 5 and is provided with end sections 7 and 8 extending anappreciable distance from the pintle 5 and bearing against therespective leaves 1 and 2 for giving the same a tendency to remain in agiven position, namely the position shown in Fig. 1. In order to make aneat appearing article, and at the same time protect the spring, asleeve 9 is provided which surrounds the spring and extends from nearone end of the hinge to the other. A notch 10 of an appreciable size isprovided in each end of the sleeve 9 in order to allow the movement ofthe extensions of the spring Specification of Letters Patent.

5 as the hinge is opened and closed. Ordinarily this would allow dirt toenter into the bearing parts of the hinge as well as produce a more orless unsightly appearance. To obviate this objection a cap 11 isprovided at each end, said cap being provided with a notch 12 merginginto an elongated opening 13 as shown in Fig. A, whereby the ends 7 and8 of the spring may freely move and the notch 10 be maintained closed.The caps 11 will, of course rotate slightly, but will not present alarge objectionable opening at any point.

What I claim is:

1. A spring hinge comprising a pair of leaves having bent up cars, apintle extending through said cars, a spring surrounding said pintleformed with an extension at each end engaging said leaves, for movingsame to a closed position, a sleeve surrounding said spring providedwith notches in each end, and a cap for each end of the sleeve havingopenings substantially fitting the extensions of said spring whereby thenotches in the sleeve are covered.

2. A spring hinge comprising a pair of leaves having cars, a pintleextending through said ears, a coiled spring surrounding said pintleformed with an extension at each end engaging said leaves, a protectingbarrel surrounding said spring and provided with notches for saidextensions whereby the extensions may freely move, and a cap on each endof said barrel covering said notches.
